The Weather was  humid during the run.  There were brief periond of lvery light showers -- not enough water to affect the course. The temperature overnight was in the low 70"s and at dawn there was quite a bit of  cloud cover. so the morining temperature was slow to rise. There was always a breeze out of the North, sometimes more of a "wind", but always welcome.  The weather did not seem to be a determining factor with regard to performance.  Seven of the eight 100K runners finished. .  In all Ultra runs combined (50K and UP) all but 2 runners finished.  Our aid stations reported a high consumption of liquids.  Usually this time of year in North Central Kansas the weather is as one expect - hot, dry, and low humidity.

Bottom line would be that the course was fine and so were the temperature and wind. The humidity though a little high was acceptable..
